Ten different 2nd grade math skills to practice in 136 task cards. These skills include arrays, fractions, counting money, telling time, addition with and without regrouping, subtraction with and without regrouping, word problems, adding 3 digits with and without regrouping, and adding 3 two-digit numbers. These task cards are great for centers because they are self-checking with a QR scanner! ***This activity would be great for digital learning and for review at the beginning of 3rd!
